    <h4 class="sectiontitle">可能原因</h4>
    <p>当CNware管理节点/计算节点负载偏高或资源数量较多时（具体规格取决于计算节点硬件能力），CNware接口响应速度变慢，导致备份软件调用接口超时失败。</p>

     <li><span>通过PuTTY或SSH工具登录CNware虚拟机客户端所在主机。</span></li>
     <li><span>执行以下命令客户端所在主机和生产环境连通性，其中xxx.xxx.xx.xx为CNware管理节点的IP地址。</span><p></p><pre class="screen">ping <em>xxx.xxx.xx.xx</em></pre> <p></p></li>
     <li><span>执行<strong>cat /<em>opt</em>/DataBackup/ProtectClient/ProtectClient-E/log/Plugins/VirtualizationPlugin/VirtualPlugin.log | grep "Http send request failed. Error is28"</strong>命令查询失败日志。</span><p></p><p>如果有回显则执行<a href="#cnware_00113__li59871696516">4</a>，否则请联系技术支持工程师。</p> <p></p></li>
